Benefits of technology

[0005] It is therefore an object of the present invention to overcome or at least ameliorate some or all of the foregoing disadvantages by providing an improved retractable rolling apparatus, relying in principle on the use of more than one sheet of material (and especially two sheets) rolled about a keyway tube of an otherwise co

Embodiment Construction

[0036] Referring generally to the drawings and in particular to FIGS. 1 and 2 there is depicted a rolling apparatus, generally referenced 11, comprising a keyway tube 12, having a keyway 13, which runs along the length thereof. The spring mechanism end 14, and idler end 15, located at each end of the keyway tube 12 are fitted with a wheel unit 16, which support the rolling apparatus 11 and allows it to roll in any suitable tracks 22.

[0037] Two sheets of cover material 17 are wound about a keyway 12. The inner edges of each sheet of material 17, not visible, are fitted within the keyway slot 13 which runs along the length of the tube 12, in known fashion (except that two sheets rather than one sheet are fitted). The two sheets of material 17 are each provided with a bar member 18 at their free ends to assist in pulling the sheets and generally supporting the free ends thereof. Wheels 20, are fitted to the ends of bar member 18 and then placed into tracks 22. One or more hooks 19 or ...

Abstract

A retractable self rolling blind, awning or cover apparatus (11), comprising two or more sheets of fabric or other suitable material (17) affixed and wound conjointly about a keyway tube (12), the tube (12) being fitted with a conventional spring mechanism for use with blinds, awnings and the like, the spring mechanism being pretensioned so as to cause the sheets of fabric (17) to be rewound about the keyway tube (12) when one or more of the sheets of fabric (17) is released from its extended or unwound position, and wherein the keyway tube (12) and spring are allowed to travel unwinding and winding up of the fabric (17).

Description

FIELD OF THE INVENTION [0001] This invention relates to self-rolling apparatus based on a conventional spring mechanism for items such as blinds, awnings and covers. However, the invention should not be construed as being limited thereto and any similar arrangement whereby the invention maybe suitably adapted is meant to be encompassed including advertising signs and the like. BACKGROUND TO THE INVENTION [0002] Conventional spring blinds are provided with a so-called hollow keyway tube onto which one end of suitable blind fabric or other material is attached, the remainder of the material being wrapped or rolled around the periphery of the tube. A spring mechanism is provided within the hollow tube, which is itself supported between suitable brackets. The blind fabric maybe caused to unroll for any desired length (up to the limit of material rolled on the tube), usually by pulling on it, which causes the tube to rotate about it's axis, thereby winding up (ie. further tensioning) the...
